Answer:
(-5, 2)
Step-by-step explanation:
Often, an arrow at the end of a graph indicates the graph extends to infinity in both the x- and y-directions. However, when the graph has a vertical asymptote at each end of its domain, it would have an arrow pointing upward, but not sideways.
<em>It is difficult to tell from this graph</em> what the intention is. It appears that there may be vertical asymptotes at x = -5 and at x = 2. If that is the case, then the domain is restricted to the interval ...
-5 < x < 2
(-5, 2) in interval notation

Answer:
Rational, Rational, Rational, Irrational, Irrational
Step-by-step explanation:
The first question:
- -√49
- -7
This number is rational
Second:
- -70.8888....
This number is rational. It wouldn't be rational if the digits won't repeat.
Third:
- 15.91
This number is rational
Fourth:
- 17π
This is irrational. The digits of pi do not repeat, making it irrational.
Fifth:
- -√14
Irrational. The square root of a non-perfect square is irrational.
